I (30F) cheated on my boyfriend (32) and I don’t know if it’s better to listen to his anger or block him.

First off, I know what I did was horrible, caused a tremendous amount of pain, broke something great. I know this makes me a horrible and shitty person. I know I don’t deserve to be spoken to kindly, to be forgiven, or have any right to ask for anything. I know this and I’ve told him this. My boyfriend of two years found out I cheated for 6 months and he has been understandably furious, horrified, and disgusted by me. I took full ownership, have tried to answer every single one of his questions honestly, even when I knew it would make me sound so much worse (worse than the horrible I’m already at). He is in so much pain and I want to do anything in my power to help. He told me to do the following: beg for his forgiveness, beg his sisters for forgiveness, his friends too, pay him back 8,000 dollars for all the dates, visit him so he can yell at me in person, be celibate for a year while he sleeps with whoever, and to give him my location. I have agreed to all that but told him I need time to do all that. He continues to be angry (understandable and expected). I am not doing this to warm his forgiveness, I’m doing it to try to make amends. Anyways, he continues to message me daily calling me disgusting, trash, scum of the earth, undeserving of love, and curses me out. I understand he is angry and maybe this heals him. I am not sure how much more of this I can take. Do you think it is better to block him/ not answer him or to continue with this? Is it truly healing him?

TL:DR: I (30F) cheated on my boyfriend (32M) of two years for 6 months. Since his finding out, I have tried to make amends by agreeing to all of his demands despite it not being with the goal of reconciliation. However, he is being very harsh with his words (understandly) and his anger seems to be worseming daily and with every answer I provide. Is it healthier to just stop answering, or do I continue with this?
